Right now, the AT&T model of the Galaxy S5 is on sale over on eBay’s Daily Deals today. It is unlocked, so it will work on T-Mobile, Straight Talk and other GSM networks. But it will not work on Sprint or Verizon, unfortunately. However, it will work elsewhere in the world. The Galaxy S5 features a 5.1-inch 1920×1080 resolution display, Qualcomm’s Snapdragon 801 processor, 2GB of RAM and 16GB of storage.
